Liquid level indicators
Liquids like mineral and silicone oils insulate and cool a transformer. You need to monitor the level of the oil to assure reliable and safe operation of the transformer. Choose our liquid level indicators and control any unexpected or accidental oil leakages that may lead to a transformer failure. Our accessories fit all transformer designs. Personalize the value settings for alarms and switches to fit your specific needs. The operator can monitor the preset values on-site through the easy-to-read dial and decide on the best transformer maintenance schedule.
